Title: Design and construction of a wheelchair with a caterpillar drive with a seat auto-leveling system
Abstract: The article presents a new version of the wheelchair, which was created as the implementation of several engineering works at the Cracow University of Technology as part of the FutureLab competition. The types of wheelchairs currently available do not allow people with disabilities to move around in any terrain. In order to be able to drive on areas such as the beach, forest but also carpet, alleys in the store, it was decided to use a tracked drive system, which additionally with its dimensions can not exceed the width of the door. In addition, an independent seat leveling system is used, which allows the seat to be tilted in two axes. Thanks to the use of inclination sensors, the system monitors and corrects the inclination on an ongoing basis, leveling the seat regardless of the curvature of the terrain. The trolley has been additionally equipped with the BMS energy monitoring system.
Key words: electric wheelchair, tracked drive, seat auto-leveling system, wheelchair control.
